I folded this out of a 6″ single-side colored Origami paper and have created a couple of extra folds on the wings to add to the ‘dragon look’. For this model, it is not important to have origami paper colored both sides. However, a larger sized paper would be more convenient and will look better too, is what I thought.
Also, another point to be noted here is to not use thick paper to fold this model. If you do so, the intricate folds at certain points will become really hard to fold and keep in place. One idea, which I have come across for folding models in Origami, is wrapping paper, which is more readily available than actual Origami paper. These come in all kinds of designs and colors, and should do perfectly fine, too.
To fold this Dragon, I have used Origami Paper Bright by Tuttle Publishing, which is a pack of 49 sheets of 6 different colors.
I have also prepared a step-by-step guide, to fold this dragon, and I hope you find it easy to follow.
